Embodiments of the present invention provide A TID-based RTWT SP that can be configured for either trigger-based transmission or EDCA-based transmission for time sensitive traffic to reduce the chance of contention/collision on time sensitive traffic caused by non-time sensitive traffic using an EDCA mechanism. This can also reduce the chance of contention on time sensitive traffic when both trigger-based transmission and EDCA-based-transmission are used in the same TID-based RTWT SP. The AP MLD can dynamically adjust the schedule of TID-SPs for ether trigger-based or EDCA-based transmission and announce the new schedule of the TID-SPs according to the requirements of time sensitive traffic and/or traffic load condition, and can prioritize time sensitive transmission to meet QoS requirements.

Receiver assisted channel access may be used during a channel occupancy time (COT). A wireless transmit/receive unit (WTRU) that is a member of a first group may receive a preamble in a first time slot set, and determine a group associated with the first time slot. On a condition that the group associated with the first time slot set is the first group, the WTRU may monitor the channel for a request-to-send (RTS) signal in the first slot set. On a condition that the RTS signal is received, the WTRU may perform listen-before-talk (LBT) on the channel. On a condition that the LBT is successful, the WTRU may transmit a clear-to-send (CTS) on the channel and access the channel in the first time slot. On a condition that the LBT is unsuccessful, the WTRU may not access the channel in the first time slot set.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications, for example, in unlicensed frequency bands. In some cases, a UE may log information associated with channel access failures on one or more frequency bands in shared spectrum and provide the information to a network entity.

Disclosed herein includes a system, a method, and a device for providing latency sensitive links. A wireless device can receive, from a wireless node, an advertisement message indicating a set of wireless local area network (WLAN) links that support one or more defined latency requirements, a capability of the wireless node to support the set of WLAN links, a plurality of parameters, an operating mode, and a status for the set of WLAN links. The wireless device can send, to the wireless node responsive to the advertisement message, a request to access a first link of the set of WLAN links. The request can indicate a capability of the wireless device to interoperate with the wireless node to use the first link. The wireless device can access the first link of the set of WLAN links if the wireless node accepts the request to access the first link.

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for priority access on a shared wireless channel. A priority station (STA), an access point (AP), or a network operator may activate a priority access service. The priority access service provides priority access to authorize priority STAs by allowing them to use more aggressive contention parameters for contention-based access of the wireless channel as compared to other STAs. In some implementations, non-priority STAs may be configured with weakened contention parameters to increase or ensure the likelihood that a priority STA will win contention for access to the wireless channel.

A typical Software Defined Radio (SDR) receiver for Binary Phase Shift Keying (BPSK) or higher order modulations accepts an incoming digital serial complex I/O channel sample stream and performs demodulation functions to recover the original baseband data stream that another source transmitted. Typically, for real-time high data rate (HDR)>5.0 Megabits per second (Mbps) operations, a SDR unit requires an Application Specific Integrated Circuit (ASIC) component or Field Programmable Gate Array (FPGA) component to perform the customized Digital Signal Processing (DSP) intensive processing functions in real-time. However, ASIC chips and FPGAs are typically relatively expensive to develop, purchase, and/or reconfigure. With the parallel multi-core algorithm method of this claim, one can now implement a real-time HDR (>5.0 Mbps) SDR Demodulator with only Commercial-Off-The-Shelf (COTS) software, a relatively inexpensive personal computer (PC) or server that contains a single multi-core General Purpose Processor (GPP), and especially without using ASICS or FPGAs.

A method performed by a user equipment (UE) includes initiating a Small Data Transmission (SDT) procedure for transmitting a first set of data packets to a base station (BS) via an uplink (UL) transmission, determining, while the UE is in a Radio Resource Control (RRC) Inactive state, whether to prioritize the UL transmission over a sidelink (SL) transmission when there is a conflict between the UL transmission and the SL transmission during the SDT procedure, where the SL transmission is for transmitting a second set of data packets to another UE.

A method and an apparatus for performing a random access procedure in a wireless communication system are disclosed. A method of performing a random access procedure according to an embodiment of the present disclosure may include receiving, from a base station, configuration information for providing information needed for the terminal to access the wireless communication system via a non-terrestrial network (NTN) including a satellite, wherein the configuration information includes first information for adjusting an orbit of the satellite and second information on common timing advance (TA); and determining a terminal-specific TA value for the terminal based on a location of the terminal and the configuration information; and transmitting, to the base station, a first message for the random access procedure at a timing determined based on the terminal-specific TA value and a common TA value derived from the second information.

Methods and apparatuses for channel occupancy indication on a sidelink (SL) in a wireless communication system. A method of operating user equipment (UE) includes receiving a SL control information (SCI) format over a sidelink channel; determining, from the SCI format, at least one of: time domain information for a channel occupancy, frequency domain information for the channel occupancy, and a SL channel access procedure. The method further includes performing the SL channel access procedure before a sidelink transmission; and transmitting, upon successfully performing the sidelink channel access procedure, the SL transmission over the SL channel within the channel occupancy based on the time domain information or the frequency domain information for the channel occupancy.

This application relates to the field of wireless communication technologies, and discloses a communication method and an apparatus, to reduce power consumption caused by invalid listening of a terminal. First, a first device sends a first message to a second device, and the second device may send the first message from the first device to a third device. Then, the first device listens to a response message of the first message from the third device in a listening time window. The response message of the first message may be sent by the third device to the first device, or may be sent by the third device to the first device via the second device.
